lets say that one Z has 300 Hp NA and another Z has 300 HP forced induction.....is the forced induction typically faster or does it have to do with other types of things such as turbo lag?

 

faster in what??? Not quite sure im understanding the question. They both have 300Hp so I would say they both are equally fast. The torque is what will be different

 

im saying like if they did quarter mile race with the same driver would it be the same times?

 

It would depend on the driver, curve of the powerband, etc.

 

depends more on the curve. NA cars are usually peaky, but put the power down more effectively. Less torque in the early RPM's so you can launch early, and more torque in the upper rpm's so they keep moving.
Turbo at 300whp and it could be as good as 100whp NA or as good as 300whp NA, depending on the setup.
SC at 300whp, and its about the same as a 300whp NA.

 

Most of the time, and I stress the most, NA hp will result in a "faster" car than the same HP but forced induction. Getting a FI car to have peak power for a long time (especially high end) is very difficult and requires $$$. This is why you will usually see big displacement NA engines in ferraris, lambos, vettes, mustangs, ect. Turbo/SC cars will usually be more powerful midrange but will let off.

 

weird question..

you have much more room to tweak the FI'd car and make it much faster. You can gain equal amount of wheel torque 300whp/300wtq.. dunno if that answers your question though.

 

this can explain why a 287 Z on the freeway is able to hang with a 300hp STi and work EVOs. on the freeway the peak of the Z keeps it going as for the STis their power drops off after 5000rpm.

i would just be upset that i had 300 hp with FI...
